If the digestive system doesn't work properly, some disorder could happen. If you're in elementary school or middle school, you're bound to giggle when you find out the first: Constipation. This is when someone doesn't use the restroom often enough and the... yeah, sits in the colon and putrifies making the individual unable to... get rid of it. Most often, this happens when an inadequate amout of fiber enters the body. Another disorder is stomache cancer. This happens when one has a diet that is high in starch and low in fiber and drinks that have nitrates. One more diease is is food poisoning. You probably know that this is when one gets very sick because contaminated food has been consumed. Symtoms are nausea, vomiting, and fever. It's more than likely at some piont in your life, you'll have one or more of these issues...Just kidding! (= (Although it is true...)
